Unless the rotors have been changed, the Renesis manual says they're 10/1.

Yeah, I know, only 16 hours. Confession time. I'm much more a
builder than a flier. I'm starting to enjoy flying the 8, but I really
like building! Going out to the hanger and spending the evening, with a
problem in mind to solve and running solutions through my head, in 3D
and rotating and changing it (like a mental CAD program) and then
figuring out the practicalities of building it with available materials
and skills or searching for other materials and others who have the
skill and tools. I miss waking up at 2:30 am with a possible solution,
writing it down so I can go back to sleep and then trying it out the
next day. These night time solutions aren't always correct, but they
almost always lead me on to the next step and the next, etc. And then
building the thing. Most things I built 3 times before I got it right.
When it's right it's RIGHT.
Then there is my personality defect. The better is always at war
with the good. Defiantly a builder thing and not a flyer thing. It
feels great to be new and better and different. And that is just the
outcome. The process is fun too. To bad it's a never ending cycle.
Not to mention there is a former Tomcat instructor out here with a clip
wing Super RV-6 with a dynoed 317 HP IO-540 in it, doing 3000 ft/min on
climb out. Not to mention the huge C.S. club he has out front. I'd
really like to have something approaching this power and have it done
with finesse and expertise rather than money and brute horsepower. I'm
not sure if the rotors in the Renesis are 9.7 or 10.0 to 1. My paper
work from Bruce says both. I think I need to talk to him about whether
the engine will handle it or not.
This whole thing is a thought experiment. I figure that to get the
NA working better I will have to build a new exhaust and intake. Build
it less fancy and more like Tracy's, paying more attention to the inside
welding and reducing flow disturbances. If I'm going to all that
work, perhaps the thing is to take it to the next level, turbo or even
20B. Major advantages and disadvantages with both routes. Anyone
other there have an extra Renesis 4 port lower aluminum intake manifold
they want to sell?
